To all whom itmuy concern:

Be it known that I, FRANK W. Henson, a citizen of the ,United States, residing at St. Louis, Missouri, have invented a certain new 5- anduseful Im-provement in Steel Car-Wheels, of which the following is a full, clear, and exact description, such as will enable others.

skilled in the art to which itv appertains to make and use the same, reference being had I to'the accompanying drawings, forming part of this specification, in which Figure 1 is an edge elevational view, partly in sectiomof my improved car-wheel. Fig.2

is a side elevational view of the same, partly in section; and Fig. 3 is.a'detail view of one of'the inserts. V Y This inventionrelates to a new and useful "improvement in steel ear-wheels,.the object being to have the body portion of the wheel made up of soft steel, such as is usually em-.

3 so that when the molten steel is poured into the mold it will flow around these inserts so that'the inserts will be cast in the tread and throat of the finished wheel.

The inserts are preferably diagonally ar-' ranged,so that contact with the rail at all times will be made by at least two or'more of said inserts, thus evenly distributing the wear over the tread and throat of the wheel. I Referring to Fig. 1, 1 indicates the body 4 portion of a cast-steel wheel, and 2 indicates the insert of hard steel which is cast therein. This insert, as shown in Fig. 2, is preferably provided with a widenedba'seportion, the contacting or upper face thereof being narrower than the bottom, so that when the molten steel flows around the insert the insert is practically dovetailed in position, thus mak- .'ing it impossible for the insert to have any play in its seat which would tend to work the 5 same loose. In addition the insert is provided with a. neck portion 3.,curved correspending to the throat between the flange and tread of the wheel, and over this neck portion the soft steel extends, asindicated by the numeral 4. The inserts of course could be made in different shapes and be provided with other means for interlocking them with the body portion of the wheel; but I believe that the tapered faces shown will provide all the interlock that is necessary or required.

I amaware that changes in the construction, arrangement, and combination of the several parts of my device could be made and substituted for those herein shown and de- J scribed withoutin the least departing from the nature and principle of my invention.

Having thus described the invention, what is new, and desired to be secured by Letters Patent, is

1. In a car-wheel, the combination of a soft- -steel body portion, and hard-steel inserts cast in the tread of the soft-steel body portion; substantially as described.

v 2. In a car-wheel, the combination of a softsteel body portion, and diagonally-arranged hard-steel inserts inserted in the tread of the soft-steel wheel and flush therewith; substantially as'described.

. 3. In a car-wheel, the combination of asoftsteel flange and tread,'and hard-steel inserts whose outer faces are flush with the soft-steel tread, said inserts having a neck portion conforming to the shape of the throat between the flange and tread; substantially as described.

4. In a car-wheel, the combination of a softsteel body portion, and hard-steel inserts arranged inthe tread thereof, said inserts being provided with means for interlocking with Y the soft steel of the body portion; substantially as described.

5. In a car-wheel, the combination of a softsteel body portion, and diagonally-arranged inserts anchored in the tread thereof, said-inserts extending up around the throat of the wheel and being capped by an overhanging .portion of the soft-steel flange; substantially as described.

In testimony whereof I hereunto afiix my signature, in the "resence of two witnesses,

this 29th day of arch, 1905.
